runners and driving wheels, we provide upon the axle differentialhousing at an upstanding spring-engaging block provided to support a rod16 secured to the hubs 6 on itsends. Over the rod 16 are expansive coilsprings 1'7 each providing an equal pressure and which will allow of aslight side movement of the 'ClflVlllg wheels with respect to therunners, but on the whole, will serve to maintain both in a truerelation.

' In cases where the ground is extremely hard and the spikes do notenter sufiiciently to give full thrust we have provided a depressingmeans consisting of spring memsecured at 19 to the body of the vehicleand at 20 to the rear axle of the car. Upon the body 1 we pivotallymount a depression lever 21 supported at 22 and provided with means 23for engaging the spring 18. Upon the end 2% we pivotally connect with alink 25 passing forward of the body and engaging with the foot lever 26pivotally mounted at 27 and with the tread 28 thereof convenient to thefoot of the operator. By reason of supporting one end of the springmember 18 upon the body and the other member upon the axle and pressingforward upon the foot lever we are able to throw considerable tensionupon the spring '18 to hold the driving wheels 11 firmly to the groundand force the spikes into the ground as by this means we. are enabled toplace thereon a portion of the weight of the body itself to secure afirm footing for the drivers.

\Vhile we have particularly described the elements best adapted toperform the functions set forth, it is obvious that various changes inthe form proportion and in the minor details of construction may beresorted to, without departing from the spirit males of this patent maybe obtained m or sacrificing any of the principles of the invention.

We claim:

1. In a motor sled, the combination with a motor body including the rearaxle, of a shaft mounted on said body directly over the rear axle andsupporting rear runners, said runners independently supporting the rearof said body and spike wheels mounted on the rear axle and contactingwith the ground through a slot in the rear runners, said rear axle beingindependent of attachment to the rear of said body and capable ofself-adjustment to the unevenness of the ground, and means whereby thewheels are flexibly supported centrally of the slot in the runners.

2. A sled attachment for autos consisting of a pair of slotted-ruimers,slotted ll'lillltll shoes therefor, supporting brackets secured to therunners and provided for axial connection to a shaft rigidly secured tothe auto body, spring means connecting with said brackets and thedriving axle to maintain the drive wheels centrally of the slots in therunners.

3. An automobile runner comprising a body with an lip-curved forwardend, a central longitudinal slot therein, having beveled wallsconverging toward the bottom, a drive wheel mounted to operate throughsaid slot and contacting with the ides thereof to be directed forcontact with the ground.

4. In an auto sleigh, the combination with a body having a rear axle, ofrear runners axially mounted to said body independently of the rearaxle, of spiked wheels mounted on the rear axle and engaging the groundthrough a slot. in the rear runners, spring tension members secured tothe axle and to the body forward of the axle and acted upon bydepressing members controlled from the foot board to throw the weight ofthe body upon the axle.

In testimony whereof we affix our signatures.
